Hi all, My building partner is looking for a really small footprint slip-ball for his panel. To this date he only found something 65x29 mm (2.56" x 1.14"). Anyone around has a suggestion as to a possible source for a smaller slip-ball ?

"Failure indications" are not normal operations . . . and yes, crew are sometimes advised to pull breakers for duration of flight as response to a failure; implementing Plan-B for comfortable termination of flight. But I'm curious as to the design of any ignition system that is not effectively shut down by simply turning it off. Was the pulling of a breaker intended to 'reset' the failure or was the breaker pulled to prevent a malfunctioning ignition from causing more mischief even tho it was commanded OFF by normal positioning of controls? I'm aware of no electronic ignition system offered to the OBAM aviation market that would require such an action . . . setting the panel control to OFF does what the label implies. Do you recall what make/model of ignition system suggested this procedure? Was it to 'reset' the light or simply disable the system for duration of the flight?

From: Rob Turk If he has an artificial horizon in his panel then perhaps he can piggy-back a slip ball onto that?

Interesting device to mount on the horizon. Unfortunately my buddy has no artificial horizon, and he insists on mounting his slip ball in the middle of his annunciator panel, hence the search for as small a part as possible.

The specific failure is t he 50% speed switch. There are 4 or 5 operational items that happened at th at time. If any one of them fail the ignition indication will remain on. Resetting the breaker will reset all of the thing that happen at 50%. Inte restingly enough this procedure was "Tribal Knowledge" on my model, the nex t model the procedure was documented in the POH.

They are resettable breakers that fit into an ATC slot. http://tinyurl.com/n4fem4d I used fuses in my first build and also in my second build. I have looked at these as a natural fit for alternator field power.

I don't think that inclinometer necessarily HAS to be installed on the artificial horizon - it would just require two tiny screws to mount anywhere on the panel. Unlikely you'll find anything smaller. Jim Parker -------- Original Message -------- Subject: Re: AeroElectric-List: Smallest possible slip-ball ?

While 'experimental' is the official designation for giving a builder something that amounts to a permanent, unbounded ferry permit, I thought the term inadequate and misleading. While we are indeed free to EVOLVE our aircraft, the vast majority of what gets licensed every year is anything but and experiment. The OBAM aircraft industry has at least met and perhaps surpassed the quality, utility and reliability of the TC aircraft. I am loath to debase our craft with a term that does not comport with reality.
